I feel that Eternas is underpowered for a planeswalker:
1)His +1 exchanges bottom to top so eventually you will get an awful card you don't want on the bottom and won't exchange it. I know you like the bottom-top card interaction, but I think it may be better just to have him allow you to shuffle instead after looking
2)his 0 ability will usually be useless, especially since the only other planeswalker in the set is karthan and unless your opponent has him on the field Eternas just has one less useful ability. Maybe something else with the bottom of your deck can be here instead; draw the bottom of your deck for 0?
Again, great work with the set!
Good job with this set, it is one of the best fan sets I have seen. The mechanics are great and work well with the plane to create that chaotic sense. My only suggestion (besides green rares which I know you are getting to) is a change in the card Molten Hills. When the similar cards like it get destroyed they give some special bonus to the player. Molten Hills simply gives you the same mana that you would have gotten had you kept it and tapped next turn. Especially if you are looking for green/red to be land discard you may want to change Molten Hills destroyed ability to be something more beneficial to the player. Keep up the good work!
